My 1996 4.3 liter gmc jimmy wont start and i have a weak spark, I changed the coil and driver along with the crank and cam sensor. I also changed the vcm and still it has a weak spark,

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

2000 gmc jimmy only starts when it wants

It don't love you any more!
You need to check and see if you're losing spark or fuel when it does not start.
Listen for the pump to buzz for about 2 seconds when you first turn the key on. No buzz could be relay, fuel pump or its circuit.
If it does not buzz, crank the engine for a few more seconds until you see the oil pressure go up. If it still does not have fuel then the pump or its wiriing may be bad.

No spark could be coil or ignition module or the wiring. Check for power to the coil. Auto Zone can test the ignition module for free. The old idea that when a module is bad its done is NOT true. The module can give intermitent problems. A vehicle can run with a bad module. If you have a tachometer and the vehicle runs smooth but the tach is bouncing, the module is bad.
The ignition module also send a signal to the PCM so it knows the vehicle is running and will send a pulse to the injectors.

My 95 gmc jimmy will turn over but won't start.

Are you getting fuel and check for spark and if all is well, then move to your fuel pump and if checks out okay , ignition module and pick up module and coil have checked out .
